Effects of Steam-pressed Corn Flakes on Performance and Egg Quality of Laying Hens
The experiment aimed to the use of some contents of steam-pressed corn to replace corn in the diet of laying hens to study the effects of corn on performance and egg quality of laying hens.A total of 10 000 40-week-old Jingfen No.6 laying hens with good health,similar body weight and egg production rate were selected and divided into the control group and experimental group by single factor experiment,with five replicates in each group and 1 000 birds in each replicate.The control group was fed a basal diet,and the experimental group was fed 100 kg steam-pressed corn to replace the corn in the basal diet.The experiment lasted for 30 days.The results showed that compared with the control group,the average daily feed intake of the experimental group was increased by 1.99%(P＞0.05),the average daily egg production rate and average egg weight were increased by 3.85%and 0.36%,respectively(P<0.05);the feed to egg ratio of the experimental group was 0.05%lower(P＞0.05).The eggshell strength and Haugh unit ratio of the experimental group were 0.03 kgf and 0.16%higher than those of the control group(P＞0.05);the egg white height of the experimental group was 0.01 mm lower(P＞0.05)than the control group.The results showed that the use of 100 kg steam-pressed corn in the diet to replace corn could improve the performance of laying hens,but there was no significant improvement in egg quality.
